m = k/m sub in the values given
-4 = k / 17
k = -68
so m = -68/n NOTE: this can also be written as n = -68/m
Answer:
Step-by-step explanation:
Nikki, they wrote the problem in a format that is general
y = k/ x for the given variables m and n then
m = k / n where k is some constant ( konstant)
plug in the given numbers for m and n
-4 =k / 17
solve for k
-4 * 17 = k
-68 = k
now we have a better formula
m = -68 / n ( this is your answer a )
now plug in -136 for m
-136 = -68 / n
solve for n
n = -68 / -136
n = 1/2 ( this is your answer b)

Which of the following is the surface area of the right cylinder below? A. 244π units B. 204π units C.869π units D.352π units
Answer is: D. 352 pi ✅
Why is that the case? Let's see.
When finding surface area, multiply two times pi times the radius times the height.
[tex]A = 2\pi rh+2\pi r^2[/tex]
Now, you need to split these four values into an actual equation.
2 followed by pi radius-height plus two pi radius, is actually the formula for surface added to the formula of area, so;
[tex]2\pi rh+2\pi r^2 = 2 * \pi * 8(radius) * 14 + 2(height~plus~the~two) * \pi * 8^2[/tex]
Solve.
the result is 1105 according to order of operations.
Divide 1105 by pi to get the answer. Pi is 3.14... so for every 3.14..., you count that as one.
[tex]1105 / 3.14 = 351.91...[/tex] which rounds to 352
Therefore, your answer is 352π units²
Thirty adults were asked how many pets they have had over their lifetime. the results are shown in the histogram below. a bar graph entitled lifetime pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20. which of the following is most likely true? the mean and median are both in the interval 1–5. the mean and median are both in the interval 6–10. the mean is in the interval 6–10, and the median is in the interval 1–5. the mean is in the interval 1–5, and the median is in the interval 6–10.
Using the concepts of the mean and of the median, it is found that the correct option is given by:
both in the interval 6–10.
What are the mean and the median of the data-set?The mean is the sum of all observations divided by the number of observations.The median is the measure that separates the bottom half of the variable from the upper half, that is, the 50th percentile.To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:
[tex]M = \frac{14(3) + 9(8) + 5(13) + 2(18)}{30} = 7.17[/tex]
The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.
Hence, the correct option is given by:
both in the interval 6–10.

20-27 show ur work
Answer:
-7?
Step-by-step explanation:
I mean, is the question 20 - 27 =? Or it's something else? Lol.
20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.
Now, I don't know if this is the question or these are set of exercises you must solve and your picture just didn't upload. Let me know if you need help with anything else.
The total cost of 5 kg orange and 3 kg apple is Rs.1100. If the rate of orange decreases by 20% and the rate of apple increases by 5%, the total cost of 3 kg orange and 3 kg apple will be Rs. 870. By what percent the cost of 1 kg apple is less or more than 1 kg orange? Find it.
The percentage that the cost of 1 kg apple is more than 1 kg of orange is 100%.
What are the linear equations that represent the question?
5o + 3a = 1100 equation 1
2.4o + 3.15a = 870 equation 2
Where:
o = cost of 1kg of orange a = cost of 1kg of apple What is the cost of 1kg of orange?Multiply equation 1 by 1.05
5.25o + 3.05a = 1155 equation 3
Subtract equation 3 from equation 2
285 = 2.85a
a = $100
What is the cost of one kg of apple?Substitute for o in equation 1
5(100) + 3a = 1100
500 + 3a = 1100
3a = 1100 - 500
3a = 600
a = $200
By what percent the cost of 1 kg apple is less or more than 1 kg orange?($200 / 100) - 1 = 100%

What is the radius of a circle whose equation is (x + 5)² + (y - 3)² = 4²?
O 2 units
O 4 units
O 8 units
O 16 units
Answer:
PLEASE MARK AS BRAINLIST
we know thatthe equation of the circle is of the formwhere(h,k) is the center of the circler is the radius of the circlein this problem we havesothe center is the point the radius is thereforethe answer isThe radius of the circle is equal to 4units
The required radius of a circle whose equation is (x + 5)² + (y - 3)² = 4² is 4. Option B is correct.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.
The equation of the circle is given by:
(x + 5)² + (y - 3)² = 4²
Comparing this equation with the standard form of the equation of a circle:
(x - a)² + (y - b)² = r²
We can see that the center of the circle is at the point (-5, 3), and the radius of the circle is 4 units (which is the same as the constant on the right-hand side of the equation).
Therefore, the radius of the circle is 4 units.
So the answer is (B) 4 units.

Answer:
D. 2(√34 + √106)
Step-by-step explanation:
1) Find the hypotenuse of a larger triangle infused in the kite since perimeter means the boundary of a shape. To do so, we need to apply the Pythagoras Theorem.
c² = a² + b²
c² = 5² + 9²
c² = 25 + 81
c² = 106
c = √106
2) Find the hypotenuse of the a smaller triangle infused in the kite.
c² = a² + b²
c² = 3² + 5²
c² = 9 + 25
c² = 34
c = √34
3) Apply the the formula for the perimeter of a kite; 2(a + b), where a is the smaller triangle and b is the larger triangle or vice versa.
= 2(√34 + √106)
In (circle)A, m∠BAD = 110. Find mDE.
Answer: 70
Step-by-step explanation: BAD is 110 degrees and BDE is 180 so do 180 minus 110 and gets you 70 which is DE
Reason:
Central angle BAD is 110 degrees.
This makes angle DAE to be 180-110 = 70 degrees since the two angles are supplementary. They combine to a 180 degree straight angle.
From there, minor arc DE is also 70 degrees. This is because the central angle subtending the arc will be the same measure.

The Angle Sum Property of a Triangle states that the internal angles of a triangle add up to 180°Here, the sum is : 130 + 30 + 30 = 190°Therefore, the angle measurements are not correctThe total angle measure of triangle should decrease by 10°By making the top angle 120°, the sum becomes 180°Hence, D is the correct option(20 POINTS AND BRAINLIEST) The rectangles below have the same perimeter
What is the area of the orange rectangle?
Answer:
Well it is 16
Step-by-step explanation:
the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4
So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16
The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16
Therefore both are 16, meaning 16 must be the perimeter for both!

What are Trigonometric Functions?Trigonometric functions are the functions which are represented as the ratio of the sides of a right angled triangle.
The three main trigonometric functions are sine, cosine and tangent function.
Sine function of an angle is the ratio of the opposite side to the hypotenuse of the triangle.
Cosine function of an angle is the ratio of the adjacent side to the hypotenuse of the triangle.
Here,
Hypotenuse of the triangle = KJ = 15 inches
LJ = 10 inches is the adjacent side with respect to the angle x.
We can use cosine function here.
cos (x) = LJ / KJ = 10/15
Hence the equation used is cos(x) = 10/15.

Work out the size of angle y
Answer:
y = 108°
Step-by-step explanation:
3x - 12 and 2x + 16 are corresponding angles and are congruent , then
3x - 12 = 2x + 16 ( subtract 2x from both sides )
x - 12 = 16 ( add 12 to both sides )
x = 28
then
3x - 12 = 3(28) - 12 = 84 - 12 = 72°
y and 3x - 12 are adjacent angles and sum to 180° , that is
y + 72° = 180° ( subtract 72° from both sides )
y = 108°
